Okay i will add more plants then. I will try to take a photo. Still very very shy. Ate earthworms today.Not cluttered at all. It’s bare.
Take a picture of the fish when it’s fins are fully flared. I find mine flare at each other after a water change. If it’s a solo fish then it might not have reason to show you it’s fins. Also not all males have obviously more blue fins or even obviously large dorsal fins.
